Clavicle Hook Plate Technique and Functional Results in the Treatment of Acromioclavicular Joint Dislocation

Abstract

Aim: The aim of this study was to evaluate the functional results of patients with acromioclavicular joint (ACJ) dislocation and who were treated surgically with Hook plate (HP) .Patients and Methods:Patients with ACE dislocation between the years of 2016- 2018 and treated surgically with clavicle KP technique were included in the study. Of the 19 patients, 17 were male and 2 were female. 13 patients had Rockwood Type IV joint dislocation and 6 patients had Rockwood Type V joint dislocation. Functional results were evaluated with modified Constant-Murley shoulder score and standard test protocol. Descriptive statistics were used for data analysis.Results: The plate was removed at 10 months after the operation due to severe pain and limitation of movement in 1 patient. Two of the patients had plate dislocation. Other patients had no complaints. Degenerative changes were detected in direct radiography in 2 patients. The mean Modified Constant-Murley Shoulder Score of the patients was 65 (min: 26, max: 84). The mean pain score of the patients was 7. Ten (53%) patients had moderate and severe pain. Four of the patients had pain at the severity of 8, 4 of the patients had pain at the severity of 10, and 2 of the patients had pain at the severity of 12. The mean daily life activity score of the patients was 12 (min: 6-max: 20). The flexion and abduction score of the patients were lower than the external rotation and internal rotation. The mean total motion score of the patients was calculated as 27 (min: 8-max: 36).Conclusion: The HP method in the treatment of ACJ dislocation is early movement and load can be given, surgery is short and easy to apply as a method. However, it causes moderate and severe pain. This may affect functional results.
